The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behavior – in conflict with our everyday ideas of what is real or local.

The quantum physics of tailor-made organic macro-molecules â€“ For the first time - as presented in Nature Communications - the quantum behavior of molecules consisting of more than 400 atoms was demonstrated by quantum physicists based at the University of Vienna in collaboration with chemists from Basel and Delaware.
